3 Description
25 µA Maximum Under Full Temperature
The TPS7B69xx device is a low-dropout linear
regulator that operates at up to 40-V VI. With only
15-µA (typical) quiescent current at light load, the
device is applicable for standby microcontrol-unit
systems, especially for always-on applications like e-
meters, fire alarms, and smoke detectors.
